1. (-4 x^2) (8 x^5)
- Multiply the coefficients: -4 x 8 = -32
- Add the exponents of x: x^2 x x^5 = x^(2+5) = x^7
- Result: -32 x^7
2. (-3 xy)
- Result: -3 xy
3. (y^5)^2
- Use the power of a power rule: (y^5)^2 = y^(5 x 2) = y^10
- Result: y^10
4. (3^4)^2
- Use the power of a power rule: (3^4)^2 = 3^(4 x 2) = 3^8
- First, find 3^4 = 81
- Then, square 81: 81^2 = 6561
- Result: 6561
5. (2x^2y)^2
- Square the coefficient: (2)^2 = 4
- Square each variable: (x^2)^2 = x^4 and (y)^2 = y^2
- Result: 4x^4y^2
6. (-2a^2 b^3)^3
- Cube the coefficient: (-2)^3 = -8
- Cube each variable: (a^2)^3 = a^6 and (b^3)^3 = b^9
- Result: -8a^6 b^9
